Police say Officer Christopher Kertis chased Dante Bonner when the 18-year-old man jumped out of a car officers pulled over at the Port Authority East Busway parking lot around 3:30 a.m.

Police said Kertis tripped and fell and Bonner fired twice, hitting Kertis twice in the leg. Kertis also had shrapnel in his foot and two broken wrists. Kertis and Officer Charles Thomas returned fire and shot Bonner, who was taken to UPMC Presbyterian in critical condition, police said.

"I had the advantage of viewing the video from the police cruiser which shows the whole incident, and he's very lucky to be alive because the individual fired two shots at him from point-blank range,” said Bryan Campbell, an attorney for the Fraternal Order of Police.

Bonner's sister does not believe the police account of what happened. She said her brother has been arrested in the past. Last month, police charged him with felony aggravated assault after a fender-bender he reportedly caused. The other car belonged to an off-duty Pittsburgh police officer who reportedly tried to detain Bonner. Court papers show the two got into a fight.

Police said Bonner told them, "If I would have known all this was going to happen, I would have KO'ed her, she just a girl," about the officer.

Hamilton wants to see her brother in the hospital and said, “They're not releasing any information, they're not letting us know about his condition or nothing, so I don't know what's going on or anything."

Because Bonner is charged with so many crimes, he is not allowed visitors in the hospital. Police plan to charge him with having a stolen gun, other firearms violations and assaulting a police officer.

Bonner was questioned but never charged with the violent killing of community activist Isaiah Dent in McKees Rocks a few months ago.

Pittsburgh police say they used evidence lifted from Mocospace after the suspect uploaded acts to the site. The girl told police that he knew she was only 13 and that he would stalk and harass her, waiting for her to get off the school bus.
